Abstract
The yield of ClO. 2 in irradiated aqueous solutions of NaClO2 has been determined by pulse and steady-state radiolyses. The yield was found to be dependent on ClO– 2 concentration but independent of pH. The solvated electron was found to react with ClO– 2 with a rate constant (2.5 ± 0.5)× 109 S–1 mol–1 dm3 to yield ClO–. In its reaction with ClO– 2 the OH. radical was found to produce two species; ClO. 2 and an OH. adduct. At sufficiently high ClO– 2 concentrations the adduct reacts with ClO– 2 producing further ClO. 2.Keywords
